Abstract
The present invention relates to a kind of mobile position-limit mechanisms of PT hand car, are set to above limit beam end, which includes limiting bracket and bolt, and the limiting bracket is in gate, and the first pin hole of interspersed bolt is arranged on crossbeam；The second pin hole is arranged on the limit beam in the corresponding first pin hole orthographic projection position；The bolt passes through the first pin hole and the second pin hole, and it is mobile to be inserted into limitation PT hand car in the limit beam.
Description
Technical field
The present invention relates to a kind of mobile position-limit mechanisms of PT hand car.
Background technique
Handcart is the main component in withdrawable switchgear, generally there is PT hand car and two kinds of (breaker) handcart of switch.
Handcart is called trolley, by taking switching on/off handcart as an example, in the case where switching disjunction, spread after guide rail can with hand by it from switchgear
Extraction, to be overhauled or to be replaced.
Handcart can move freely on guide rail, as long as in need, can directly extract out；But as power equipment key portion
Part, handcart extraction is improper to occur safety accident, and there are security risks, it is therefore desirable to set up an organization to limit freely taking out for handcart
Out.
Summary of the invention
It is an object of the invention to: a kind of structure is simple to solve the above problem, the reliable PT hand car of limit is mobile
Position-limit mechanism.
The technical solution adopted by the present invention is that such:
A kind of mobile position-limit mechanism of PT hand car, is set to above limit beam end；The mechanism includes limiting bracket and inserts
Pin, the limiting bracket are in gate, and the first pin hole of interspersed bolt is arranged on crossbeam；Corresponding first pin hole is just thrown
The second pin hole is arranged on the limit beam in shadow position；The bolt passes through the first pin hole and the second pin hole, is inserted into institute
It is mobile to state limitation PT hand car in limit beam.
Further, further include screw, limiting slot is set on one side girder of limiting bracket, the screw passes through limit
Slot is vertical with bolt connect for position.
Further, the limiting slot is located at limiting bracket towards on a side girder of handcart entrance.
Further, which is set to handcart inlet.
In conclusion due to the adoption of the above technical scheme, the beneficial effects of the present invention are:
Mechanical limit structure of the present invention is more reliable and permanent secure, and can limit in trolley arranged on left and right sides and be respectively provided on beam
The mechanism is to make dual fail-safe.
Detailed description of the invention
Fig. 1 is drawer-type switch cabinet PT hand car part-structure top view；
Fig. 2 is present invention structure chart in trolley work；
Fig. 3 is present invention structure chart in trolley extraction；
Fig. 4 is Fig. 2 side view.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and examples.
As shown in Figs 1-4, the mobile position-limit mechanism of a kind of PT hand car is set to above limit 1 end of beam of trolley two sides, position
In switchgear trolley inlet；
The mechanism includes limiting bracket 2, bolt 3 and screw 4, and the limiting bracket 1 is in gate, and setting is interspersed on crossbeam
The first pin hole (being not drawn into figure) of bolt, towards handcart inlet side stringer on be arranged limiting slot 21；The screw 4 is worn
Cross that limiting slot 21 is vertical with bolt 3 to be connect；Limiting slot 21 limits screw 4 or so, upper and lower position, and screw 4 connects with bolt 3
It connects, to realize the restriction to 3 position of bolt；The corresponding first pin hole orthographic projection position is arranged on the limit beam 1
Second pin hole (is not drawn into) in figure；The bolt 3 passes through the first pin hole and the second pin hole, is inserted into the limit beam 1
Car wheel is blocked, limitation PT hand car is mobile.
When handcart needs to pull out, bolt 3 is lifted or directly portable bolt 3 and is tiltedly placed in limit beam by hand-holdable screw 4
On 1, wheel can be freely accessible at this time, be also by this execution when should need for PT hand car to be pushed into together.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
